Nokia World Nokia Research Bluetooth 3D indoor positioning system
Nokia was also demoing a 2D indoor positioning system, which in this case was set up to track various Nokia employees as they moved around the ExCel Centre, pictured above in 3D model form.
The tracking tech uses Bluetooth low energy with a tracking layer built on top of it. The system requires each floor of a building to be furnished with one Bluetooth antenna which can then triangulate the position of employees wearing trackable tags as they move about the space. Gates or zones can be added to the map so the system is able to count the number of tagged people passing through or occupying particular indoor areas.
One of the advantages of this system over other indoor technologies that can fix position, such as wi-fi, is its high degree of precision, according to Nokia. Nokia envisages enterprise applications such as tagged trolleys and supermarket baskets arriving first - perhaps as early as next year - before any consumer applications.
